Basal Insulin Fc (BIF; LY3209590) , a fusion protein combining a novel single-chain insulin variant with a human IgG Fc domain, is designed for QW administration. This randomized, parallel, open-label Ph2 study assessed safety and efficacy of BIF vs. DEG in insulin-naïve patients with T2D previously treated with oral antihyperglycemic medication. BIF was injected QW, and DEG was injected QD. Both groups were titrated to fasting blood glucose (FBG) ≤100 mg/dL. The primary endpoint was HbA1c change from baseline (CFBL) to Wk 26 (non-inferiority margin=0.4%) . Patients randomized to BIF (N=129) and DEG (N=135) had a mean age of 58.4 yrs and baseline HbA1c of 8.0%. After 26 wks, BIF showed non-inferiority vs. DEG for HbA1c CFBL with a treatment difference of 0.06% (90% CI = -0.11, 0.24; p = .56) , and both groups had >75% time in range (70-180 mg/dL) on average at Wk 26 (Figure) . BIF and DEG significantly reduced FBG from baseline (treatment difference BIF vs. DEG = 4.7 mg/dL [90% CI = 0.1, 9.3]; p = .09) . Rate of Level 2 hypoglycemia was low and not significantly different (BIF = 0.22; DEG = 0.15 events/pt/yr; p = 0.64) . Occurrence of treatment-emergent adverse events was similar between BIF and DEG. QW BIF achieved excellent glycemic control similar to DEG with no concerning hypoglycemia or other safety findings, supporting continued development of BIF in Ph3. Disclosure J.M.
